What is the correct name of the color? Fuchsia, tyrian purple, magenta, maroon? Maybe fascinating? Puce? Dark pink? Dusty Rose? Vermillion? My agent and I are having no end of arguments about the name of the color. Famous Actress

5 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Famous Actress Color names are ambiguous Just buy a spectrophotometer and measure the darn dress

7 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, Do you agree using RHEM indicators on digital proofs for customer approval is a good idea? How do you respond to those smaller, less technical customers (mom & pop) who are unable or unwilling to purchase a light booth? Breaking Brad

8 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Breaking Brad, Key phrase: If stripes are seen, light not 5000K Does not mean If stripes are not seen, light is 5000K If you turn off the lights you wont see stripes, but the light is definitely not 5000K!

9 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, I was painting my toenails a lovely lavender to match the cover of the latest GLAMOUR magazine, but when I went outside the next day the color was all-wrong and I had to redo them!!!

19 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, Every time I go on a press ok, and I see a guy running color, I cringe. I mean – most guys are colorblind, right? Fed up With Bad Color

20 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Fed up with Bad Color, Yes, there are more color deficient men than women No, not all men are not colorblind

21 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Global Incidence of Red-Green Color Deficiency Ethnic GroupMalesFemales Europeans8%0.5% Asians4%0.6% Africans2.6%0.5% Australian Aborigines2.0%0.03% American Indians1.9%0.6% South Pacific Islanders0.8%0.0% The X chromosome carries the genes for Red and Green photosensors. Men have one X chromosome and women have two, so a defective genetic sequence is more likely in males. On the other hand some evidence has been reported that defective genetic sequences in women can occur in one X chromosome but not in the other producing tetrachromatic vision in maybe 6% (estimated) of women.

33 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, I dont really have to think about people with color deficiency when I design, do I? I mean, its just too hard to figure out what someone would see, anyway. Right? Color sufficient and proud

34 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Sufficient and Proud, Yes you do, and no it isnt

37 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, I heard your response to the question about color blindness, excuse me, color deficiency in men. I passed the Ishahara test, so I must belong to the 90% of men who are not color deficient. Still, I just dont seem to be as sensitive to color differences as my wife. Why is that? Just call me insensitive

38 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Just Call Me Insensitive, Men who are not color deficient are still less color conscious than women Likely a nurture issue rather than nature

39 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Fun Factoid 9 out of 10 men agreed that the right answer to their wife isYes Dear. The 10 th man has not been heard from since.

43 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Hardware Hank, Dont try this at home! Compare the cost of a booth to the cost of losing a big account

52 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, Please help me figure out the punch line to this joke. An ad agency exec, a prepress technician, and a printer walked into a color booth… Shirley you must be joking

53 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Shirley You Must be Joking, Stop calling me Shirley! We have identified perceptual differences due to Color deficiency, age, fatigue, medications, tinted glasses Lighting, metamerism, surround There are also perceptual differences due to context

54 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Whats Your Focus? Merino Cardigan $59.99

58 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Desperate in Des Moines, If only you would have been listening when Danny talked about metamerism!

59 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, I print for a high-end cosmetics company. They provide me with files and proofs to the GRACoL print aim. The Purchase Order requests me to print on an SBS stock that clearly does not meet the GRACoL paper specification. How can I print on SBS that will simulate the GRACoL file? How can I proof back to the customer what my printing will look like on the SBS? How can I get my customer to understand that what I print will not simulate what they sent me? Beauty in the Proof

60 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Beauty in the Proof, All is not lost

61 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Beauty in the Proof,

64 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, One of my clients art director is causing me sleepless nights, he is always complaining that everything we do for him is too red. I'm at my wits end trying to educate him on what we do to make sure the proofs and prints are reproduced accurately – all to no avail. Any words of wisdom? Sleepless in Seattle

65 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Sleepless in Seattle, Whats wrong with this picture of the art director?

66 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Color Maven, We have our first Job being printed by multiple plants across multiple companies. We have one source making good standard proofs and everyone will be printing on the same stock. Can we expect that each press operator will see the same color in our proofs? Is it reasonable to expect that we will receive a close simulation of our proof from all these plants? Confused in Connecticut

67 I D E A l l i a n c e a t P R I N T 1 3 – B o o t h # Dear Confused in Connecticut, No, you cant expect everyone to see color the same But… It is reasonable to expect that proper Color Management will give you a close simulation
